From a window 40 feet above the ground in a certain building, the angle of elevation to a window in a second building is 43 degrees. If the distance between the buildings is 110 feet, how far above ground level is the second window? If x + 40 is the height of the second window, the first step is a. tan 43 degrees= x/110 b. sin 43 degrees= x/110 c. sin 43 degrees= 110/x d. tan 43 degrees= 110/x
